Prevent Hot Linking to images

To stop other sites directly linking to your images and media files and stealing your bandwidth You need to add following code in your .htaccess file

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www.)?domain.com(/)?.*$ [NC]
RewriteRule .*.(gif|jpg|jpeg|bmp|wmv)$ http://www.domain.com/image.jpg [R,NC]

Note: replace your website with domain.com
